Hi HN,We’re Ruben, Afnan, and Theo, and we’re building Davia to solve a common problem: documenting and explaining large codebases is complex. It takes too long to generate even a first draft of a wiki, visuals are essential to understand the structure, internal docs should be editable in the IDE, and most solutions aren’t open.Davia is an open source tool. You enter the path of your repo, and it generates a visual wiki you can explore and edit. Diagrams are created automatically, and you can update everything either in your IDE or in a Notion-like editor.The project is still early, and we’d love to hear feedback, ideas, or experiences from anyone interested in documenting and sharing code internally.GitHub: https://github.com/davialabs/davia

Could you build this?

Yes Generating visual docs and wikis from code involves traversing local files, generating ASTs or directory trees, sending code summaries to LLM APIs, and displaying diagrams via tools like Mermaid.js.

Competitors mentioned: DeepWiki, AI SDK, E2B, GPT OSS, Transformers

Concerns raised: High token usage and processing time (300K-1M tokens, ~2 minutes per repo), IP/privacy concerns with vendor API keys mining codebases, AI-generated documentation may paraphrase rather than provide meaningful explanations, Permission/overwrite conflicts when code changes after documentation edited, Requires vendor API keys instead of local model support

Feature requests: Add examples with real complex projects (React, three.js, Spring), Include non-AI open source projects in showcases, Local model support for full privacy, Fix navigation UI (hamburger icon hijacking main site navigation)
